Compound Actuating Tool Integrated Geared Teeth Leverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compound actuating tools, such as pliers, often require separate geared mechanisms attached to handles or jaws, which complicates manufacturing and may not efficiently multiply force.
Innovation Solution
Integration of two sets of geared teeth directly into the handles and jaws of pliers, along with a biasing element, allows for a compound leverage system that increases the force exerted by interfacing surfaces when gripping, eliminating the need for a separate pawl and simplifying manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a separate geared mechanism (e.g., pawl) is attached to handles or jaws, then force multiplication is achieved, but device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The patent integrates the geared teeth directly into the handles and jaws, merging the force multiplication mechanism with the structural components. This eliminates the need for a separate pawl and reduces device complexity while maintaining the compound leverage effect.
Solution Approach 2:
The handles and jaws serve dual functions: as structural components and as the geared mechanism itself. The teeth integrated into these components perform both structural support and force multiplication, reducing the number of separate parts needed.
2Force
If a separate geared mechanism (e.g., pawl) is attached to handles or jaws, then force multiplication is achieved, but manufacturing complexity increases
Solution Approach 1:
By combining the geared teeth with the handles and jaws into integrated components, the patent reduces the number of separate parts that need to be manufactured and assembled. This simplifies manufacturing processes and reduces assembly steps while maintaining the force multiplication capability.
3Device complexity
If geared teeth are integrated into handles and jaws, then device complexity is reduced and manufacturing is simplified, but force multiplication efficiency may be compromised
Solution Approach 1:
The integration of geared teeth into the handles and jaws maintains the compound leverage system's force multiplication capability. The first set of teeth on the first jaw and the second set of teeth on the second jaw work together to provide mechanical advantage, ensuring efficient force multiplication.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated teeth system in pliers provides similar force-multiplying effects to conventional designs while being easier to manufacture, enhancing the efficiency and usability of the actuating tool.
Implementation Method 1
a biasing element coupled to the second component and the second jaw such that the second jaw is moved with the second component
Implementation Method 2
two sets of geared teeth are integrated into the handles and/or jaws
Implementation Method 3
the first plurality of teeth engage the second plurality of teeth

AI summary
A clamping tool, such as pliers, is provided. The clamping tool includes a pair of components coupled to a pair of jaws. The first component and the first jaw include a first set of teeth that engage with a second set of teeth included in the second component and second jaw. The engagement between the teeth provide a compound leverage system.
